1 Claim. 1

This invention relates to mop holders, wherein the mop holding structure is composed of variable elements.

Due to the various types of surfaces encountered in mopping operations, it is desirable to utilize a mop holder whose form can easily be revised to conform to the particular surface on hand. Moreover, to facilitat replacing or repairing of the mopping element, a mop head of the detachable variety is of prime importance.

Consequently, the primary object of the present invention is to provide a mo holder which has a screw operated sliding jaw and which comprises an elongated supporting bar formed with a centrally normally projecting hollow tube adapted to retain a mop handle, which bar includes transverse perforations near the bar ends, and also a stud which projects from the bar side remote from the tube and which also includes a retaining bar formed with a central hole to receive the stud, and further includes attachment means adjacent the retaining bar ends in alignment with the said perforations, and fastening means whereby the two bars may be drawn together to exert a gripping pressure upon a mopping element insertable between the bars, and the bars comprise substantially fiat rectangular plates having parallel planar opposing surfaces; and the retaining bar has its under surface recessed at areas in alignment with the attachment means which comprise bolt and nut assemblies, and the retaining bar has holes adjacent its ends and the bolts extend through the retaining bar holes and the perforations; the bolt heads lie within the recess whereby no portion of the bolts extends beyond the lower surface of the retaining bar; and finally, in which the retaining bar has a centrally raised portion on its underside, which raised ortion has edges and is of a width narrower than that of the retaining bar, and the raised portion is adapted for removal by its edges of spots or dirt adhering to the floor.

Other objects and structural details will become apparent from the description and accompanying drawings wherein:

Figure 1 is a perspective view of the invention.

Figure 2 is an exploded perspective view of the two parts comprising the invention.

Figure 3 is a cross-sectional view thru 33 of Figure 1.

Figures 4, 5 and 6, show various modifications of the basic inventive concept.

Referring to the drawings, the mop handle i0 is secured to the improved mop holder assembly ll by the retaining means I2, comprising the 2. hollow connection tube 13 provided with the bolt and nut assembly l4, whereby the handle l0 can is? reznoved by removing the bolt and nut assem- Referring to Figure 2, the holder assembly ll comprises the tube l3 extending from the base plate which is perforated at l 6' and IT. A stud l8 projects from bar is at a point directly below the tube l3.

The mopping element [9 is secured to the bar 15' by the retaining bar comprising the elongated plate 2|, having the central perforation 22, and the recessed end perforations 23 and 24-. In Figure 2 it is better seen that the under side of bar 29 is formed with the raised portions 25, 26 and 21, providing the recessed areas 28 and 29' through which the perforations 23 and 24 are formed. The centrally raised portion 26 contains the central perforation 22. The centrally raised portion 26 serves particularly the purpose to permit the removal of any spots or dirt adhering to the floor by using the edges of the portion 28.

In operation, the mop assembly is made by inserting the mopping element 19 between the bars [5 and 20 and wrapping one of the free mop ends about the lower bar 20 as shown in Figure 1. The lower bar 20 is secured to the upper bar l5 by centering perforation 22 about stud l8 whereby perforations i1 and I6 are brought into alignment with perforations 23 and 24 respectively. The bars are pressed together firmly gripping mopping element I9 by nut and bolt assemblies 30 and 3|. It is to be noted that by the provision of recesses 28 and 29, the bolt heads 32 and 33 do not protrude from the under surface of bar 20, thereby eliminating the possibility of injurious contact between the bolt heads and the serviced surface.

By means of the simple but efficient mop holder disclosed in the foregoing description, the removal or insertion of a mopping element can rapidly be performed. Moreover, there are presented no protrusions liable to injure the areas to be mopped. The mopping element is firmly grasped without resorting to the conventional teethlike biting means which result in a torn defective mopping element.

In the form depicted in Figure 4, the parallelepiped form of the bar 20 of Figure 3 is replaced by the cylindrical bar 34 which eliminates the sharp corners of the rectangular form and reduces the zone of gripping pressure to the line-of tangency between the upper and lower bars.

In the modification of Figure 5, both the upper and lower bars of Figure 3 are replaced by the 3 cylindrical elements 35 and 36 with a view to eliminating all sharp edges for obvious reasons. The form depicted in Figure 6, is derived from that seen in Figure 5 by replacing the separable bolts with the integral studs 3! and 38, thus eliminating the necessity for recessing the underside of the lower bar. As mentioned in the above, the recesses provided in the under side of the lower bar (see 28 and 29 of Figure 2) provide space for the bolt heads whereby the bolt heads would not project from the bottom surface. In the instant form, the provision of the integral lug means eliminates the necessity for such recesses. Obviously, the form of the bars in cross section need not be cylindrical as depicted in Figure 6, such cylindrical shape merely being employed for illustrative purposes.

The material used in fabricating the disclosed device may be plastic, metal, wood, rubber, etc.

Since a plurality of species of the various combining elements have been disclosed, it should be obvious that the possible combinations of such species in addition to other modifications involving shape, dimension and material, are all herein contemplated and considered within the inventive scope as defined in the claim.

Having thus set forth and disclosed the nature of this invention, what is claimed is:

A variable mop holder comprising an elongated supporting bar formed with a centrally normally 1 projecting hollow tube adapted to retain a mop handle, said bar including transverse perforations near the bar ends, a stud projecting from the bar side remote from the tube, and including a retaining bar formed with a central hole to receive the said stud, including attachment means adjacent the retaining bar ends in alignment 4 with the said perforations, and fastening means whereby the two bars may be drawn together to exert a gripping pressure upon a mopping element insertable between the bars, wherein the bars comprise substantially flat rectangular plates having parallel planar opposing surfaces, the retaining bar having its under surface recessed at areas in alignment with the attachment means, said fastening and attachment means comprising bolt and nut assemblies, said retaining bar having holes adjacent its ends, said bolts extending through the retaining bar holes and the perforations, the bolt heads lying within the recesses, whereby no portion of the bolts extends beyond the lower surface of the retaining bar, the said retaining bar having a centrally raised portion on its underside, which raised portion has edges and is of a width narrower than that of the said retaining bar and the said raised portion being adapted for removal by its edges of spots or dirt adhering to the floor.
